Formação de biofilmes monotípicos e heterotípicos por Enterococcus faecalis E Enterococcus faecium em dentina radicular

E. faecalis e E. faecium possuem grande relevância nas infecções hospitalares por apresentarem facilidade em adquirir resistência aos antibióticos. E. faecalis também apresentam alta prevalência nas infecções endodônticas, entretanto a importância de E. faecium para a odontologia ainda precisa...

Do different strains of E. faecalis have the same behavior towards intracanal medications in in vitro research?

Abstract: The aim of this study was to evaluate the antimicrobial action of different endodontic pastes against Enterococcus faecalis ATCC 29212, isolated from the urinary tract, and compare the action with E. faecalis ATCC 4083, isolated from the root canal. For this purpose, dentin blocks were infected...

Demetallization of Enterococcus faecalis biofilm: a preliminary study

J. appl. oral sci; 26 (), 2018
Abstract Objectives To determine the concentration of calcium, iron, manganese and zinc ions after the application of chelator to Enterococcus faecalis biofilms. Material and Methods Fifty bovine maxillary central incisors were prepared and inoculated with E. faecalis for 60 days. The following were ...

Efficacy of relacin combined with sodium hypochlorite against Enterococcus faecalis biofilms

J. appl. oral sci; 26 (), 2018
Abstract Objective Relacin is a synthetic molecule that targets RelA, an essential protein in a conserved bacterial stress response system. It was shown to inhibit bacterial growth. The aims of this study were to evaluate the antimicrobial effect of relacin combined with sodium hypochlorite (NaOCl) on ...

Evaluation of physical-mechanical properties, antibacterial effect, and cytotoxicity of temporary restorative materials

J. appl. oral sci; 26 (), 2018
Abstract The objective of this study was to compare selective physical-mechanical properties, antibacterial effects and cytotoxicity of seven temporary restorative materials (TRM): five resin-based materials [Bioplic (B), Fill Magic Tempo (FM), Fermit inlay (F), Luxatemp LC (L) and Revotek LC (R)], and z...

Quorum sensing LuxS/autoinducer-2 inhibits Enterococcus faecalis biofilm formation ability

J. appl. oral sci; 26 (), 2018
Abstract Objective: To investigate the relation between biofilm formation ability and quorum sensing gene LuxS/AI-2. Materials and Methods: Enterococcus faecalis (E. faecalis) standard strain ATCC 29212 was used in the study. Long flanking homology polymerase chain reaction method was used to build the...

Efetividade de diferentes medicações intracanais no combate ao enterococcus faecalis
Effectiveness of different intracanal medications in combating Enterococcus Faecalis

Rev. Salusvita (Online); 37 (3), 2018
Introdução: a medicação intracanal deve ter excelente propriedade antimicrobiana e apresentar baixa toxicidade. O Enterococcus faecalis é um microrganismo resistente e raramente encontrado em infecções primárias, mas predominante em retratamentos endodônticos. Objetivo: discutir sobre a eficáci...

Antibacterial effect of four endodontic cements against enterococcus faecalis ATCC 29212: an in vitro study

J. oral res. (Impresa); 6 (12), 2017
Objective: to compare the in vitro antibacterial effect of the root canal cements Endobalsam, Top Seal, Apexit and Endofill against enterococcus faecalis ATCC 29212. Materials and method: Eighty-five applications of cements on enterococcus faecalis, cultured in vitro on solid media in Petri dishes, were ...

Intradentinal antimicrobial action and filling quality promoted by ultrasonic agitation of epoxy resin-based sealer in endodontic obturation

J. appl. oral sci; 25 (6), 2017
Abstract The aim of this study was evaluate the influence of ultrasonic activation (UA) of AH Plus to improve canal and isthmus filing, and analyse the antimicrobial effect against Enterococcus faecalis within dentinal tubules. Material and Methods: Thirty mesial roots of mandibular first molars were se...

Effect of ultrasound streaming on the disinfection of flattened root canals prepared by rotary and reciprocating systems

J. appl. oral sci; 25 (5), 2017
Abstract New technical and scientific developments have been advocated to promote the success of the endodontic treatment. In addition to rotary and reciprocating systems, irrigating solution agitation has been suggested and passive ultrasonic irrigation (PUI) is the most used. Objective: To evaluate, in...
